THOMAS UTLEY, OF LIVERPOOL, ENGLAND.

LIGHT AND AIR PORT FOR SHIPS.

SPECIFICATION forming part of Letters IFatent No. 591,707, dated October 12, 1897. Application filed April 27, 1897. Serial No. 634,165. (No model.)

To all whom it may concern:

Be it known that I, THOMAS UTLEY, engineer, a subject of the Queen of Great Britain, residing at Sefton House, Crosby Green WVest Derby, Liverpool, in the county of Lancaster, England, have invented certain new and useful Improvements in a Combined Light and Ventilator for Ships, of which the following is a specification, reference being had to the accompanying drawings. I

This invention relates to ships lights so constructed that by moving the glass-holder to and fro in the frame a ventilation-opening of more or less capacity, according to the adj ustment of the holder, is provided. The said lights are applicable for deck-houses and for ships sides.

For the purposes of my invention I make the frame, which projects inboard a suitable distance, larger at the outer end than at the inner end, and I provide the glassholder with square or equivalent pivots or lugs at top and bottom to slide in guideways formed in or applied to the frame, or I arrange the glassholder to work upon screws, by which it is moved in and out. The glass-holder is constructed, as heretofore, with a bead or flange on its inner face to make a tight joint, with an india-rubber seating-ring arranged in a flange of the frame, and is furnished with the usual hinged screw-bolts and lugs for securing it tightly in place when required. By loosening the securing bolts and then sliding the glass-holder outwardly in its guides or moving it by means of the screws an opening is made all around the holder for the admission of air, such opening increasing in capacity the farther the glass-holder is pushed out, so that by adjusting the position of the glass-holder the air-current can be regulated as desired.

In combination with the aforesaid light I sometimes provide a grid-ventilator facing outward at the upper part of the frame above the glass-holder,said ventilator being adapted to admit airbehind the glass-holder when the latter is open and so increase the ventilation.

Referring to the accompanying drawings, which illustrate a side light constructed according to my invention, Figure 1 is an elevation of the light as seen from outside the ship or from the ships deck. Fig. 2 is a vertical central section, and Fig. 3 is a horizontal central section, of the light; and Fig. 4 is a section of a portion of the light, illustrating a modification, hereinafter described.

Like letters of reference denote corresponding parts in the several figures.

A is the frame of the light, which is secured to the ships side or deck-house in the usual or in any convenient manner. The said frame projects inboard a suitable distance, as indicated in Figs. 2 and 3, and the sides of it are'tapering, so that the inner endis smaller than the out-er end.

B is the glass-holder, constructed with square pivots or lugs B B at top and bottom, the same being arranged to slide in guides O 0, formed in or secured to the frame A. The glass-holder can thus slide in and out a suitable distance, but cannot turn.

D is a removable cover-plate which is secured to the frame after the glass-holder has been placed in position to prevent the glassholder from being pushed out too far. I have shown a rectangular frame and glass-holder, but they may be square or oval or of othe desired shape.

The inner end. of the frame is constructed with an inturned flange A, adapted to receive the'usual india-rubber jointing-ring E, for making a secure Water-tight joint with a bead or flange B formed around the edge of the glass-holder.

E Eare the hinged bolts for screwing the glass-holder tightly home when it is desired to close thelight. These bolts are constructed and secured in the usual manner.

It will be observed that by reason of the taper formation of the frame A an opening for admitting air Will be formed around the glass-holder when the latter is pushed back, and the farther the glass-holder is pushed back the larger will be the opening thus formed, so that a means is thus afiorded of regulating the size of the ventilation-opening by adjusting the position of the glass-holder in its frame. In addition to the opening thus afforded I prefer to construct the light when used in a deck-house with a ventilation-grating E at the top, through which air can pass into a chamber or cavity F, whence it passes through holes in the plate G and enters the vessel when the glass-holder is pushed back.

In order to prevent rain, sea-water, or spray from beating inboard through the gratings when the light below is open, I provide a sloping shield II within the chamber F so arranged as to drain off any rain, seawater, or spray that may enter through the outer grating E. The flange A prevent-s rain, sea-water, or spray from beating inboard around the glassholder except when the latter is fully open.

In lieu of the ventilator above described I sometimes use at the top of the light a trunkventilator of the kind described in the specification of my prior patent, No. 495,856.

r In Fig. i I have shown a modification according to which the glass-holder is adjusted by screws K, passing through the lugs 13 of the glass-holder. The said screws also serve as guides for the glass-holder in lieu of the guides O.

IVhat I claim is 1. In a ships light and ventilator the combination of a fixed frame projecting inboard and having taper sides, guides at top and bottom of said frame, and a glass-holder constructed with pivots or lugs at top and bottom which slide in said guides, substantially as described.

2. In a ships light and ventilator, the combination of a fixed frame projecting inboard and having taper sides, guides at top and bottom of said frame, a glass-holder constructed with pivots or lugs at top and bottom which slide but cannot turn in said guides, a plate to limit the outward movement of the glassholder, a flange at the inner end of the frame furnished with an indiarubber ring to make a tight jointwith the glass-holder, and means for screwing the glass holder against said flange, substantially as described.

3. In a ships light and ventilator, the combination of a fixed frame having taper sides, a glass-holder which is adjustable to and fro in said frame, and a ventilator at the top of the frame, substantially as described.

4. In a ships light and ventilator, the combination of a fixed frame having taper sides, a glass-holder which is adjustable to and fro in said frame, a grating-ventilator at the top of the frame, and an inclined shield II to prevent rain from beating inboard through the ventilator, substantially as described. I

In witness whereof I have hereunto set my hand this 17th day of April, 1897.

THOMAS UTLEY.
